Fruit identification method based on multi-source image information fusion

The invention provides a fruit identification method based on multi-source image information fusion and relates to the technical field of automatic identification of fruits under the natural environment. The method comprises the following steps: using a vision system combined by a depth camera and a color camera, s synchronous collecting a multi-source image to conduct preprocessing, and obtaining an image to be registered; conducting precise registering for the image to be registered; conducting pixel-level image fusion on an image which is precisely registered, and obtaining a pixel-level fusion image; and conducting identification on a fruit area in the pixel-level fusion image. The method overcomes the defect that a single imaging sensor collects an image to conduct fruit recognition, improves accuracy of fruit recognition, reduces effect of fruit non-structural environment on identification, and achieves reliable identification of the fruit area.
